The black-capped warbling finch is a species of bird in the family Thraupidae. It is found in Argentina, Bolivia, Brazil, Paraguay and western Uruguay. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical dry shrubland, and subtropical or tropical high-altitude shrubland.
Region
Southern Cone and Gran Chaco
Typical Environment
Occurs across northern and central Argentina, eastern Bolivia, southwestern Brazil, Paraguay, and western Uruguay. It favors dry forests, thorny scrub, and semi-open brushlands, including the Gran Chaco and Monte-like shrublands. In foothill zones it uses high-altitude shrub and open woodland. It readily occupies edges, clearings, and second-growth scrub near grasslands and agricultural mosaics.
Altitude Range
0–2500 m

Also known as a warbling-finch, it belongs to the tanager family (Thraupidae) and was formerly placed in the genus Poospiza. The name refers to its striking black cap, which contrasts with a gray face and paler underparts. It adapts well to dry, shrubby habitats and often forages in small groups. Its sweet, warbling song is frequently delivered from exposed perches.
Temperament
social and active
Flight Pattern
short rapid wingbeats
Social Behavior
Typically seen in pairs or small groups and may join mixed-species flocks in the non-breeding season. Nests are cup-shaped and placed low in shrubs or small trees. Pairs are likely monogamous during the breeding season and defend small territories.
Migratory Pattern
Resident
Song Description
A clear, sweet warble composed of melodious whistles and trills. Males sing from exposed perches, with phrases repeated and interspersed with softer call notes.
Plumage
Gray head with a distinct black cap, brownish to olive-brown upperparts, and pale whitish underparts with buffy flanks; often shows faint wingbars.
Diet
Consumes small seeds, berries, and a variety of arthropods gleaned from foliage and the ground. Insects and spiders are taken more frequently during the breeding season to provide protein. It will also pick at seeding grasses along edges and disturbed areas. Diet flexibility allows it to use semi-open and scrubby habitats year-round.
Preferred Environment
Forages in low shrubs, brushy edges, and on the ground within dry forests and thorn scrub. Often uses ecotones such as fence lines, field margins, and regenerating second growth.
